I need some help with Powershell and WPF.
I am modifying an Add-In that someone made using WPF and powershell. So I'm not 100% sure how the xaml structure is laid out. What I want to do is to modify the Text property of a certain element that is generated during runtime. I used Snoop2.8.0 and found the element that I want to modify, and it has a Name property "FreeTextBox". I intend to use the FindName method to get to the element, however, the FindName method returns nothing.
I have read in a few posts that there is a separate thing called contentPresenter where these runtime elements are stored and that I need to reference it to get to my textbox, however, I don't know how to do this. I would appreciate if anyone could point me in the right direction.
Regards Ilyas

As can be seen in the last line of this second code, I am trying to get use findname to get the FreeTextBox that was created from the main application. Unfortunately I don't have the code that creates the textbox as this is an addin that calls from the main application. I used snoop to find out the properties of the element itself, but stack doesn't allow me to post images yet.
The FreeTextBox is probably in another usercontrol, or datatemplate loaded to your window and therefore is in different NameScope. FindName looks for elements only in current namescope.
you need to recursively traverse entire visual subtree of the window using VisualTreeHelper API and check name property of each element in order to find the FreeTextBox. Just use GetChildrenCount and GetChild methods.
